Can predictive models be used for causal inference?

no code implementations18 Jun 2023 Maximilian Pichler, Florian Hartig

Here, we show that this trade-off between explanation and prediction is not as deep and fundamental as expected.

cito: An R package for training neural networks using torch

1 code implementation16 Mar 2023 Christian Amesoeder, Florian Hartig, Maximilian Pichler

Most current deep learning (DL) applications rely on one of the major deep learning frameworks, in particular Torch or TensorFlow, to build and train DNN.

The evidence contained in the P-value is context dependent

no code implementations26 May 2022 Florian Hartig, Frédéric Barraquand

In a recent opinion article, Muff et al. recapitulate well-known objections to the Neyman-Pearson Null-Hypothesis Significance Testing (NHST) framework and call for reforming our practices in statistical reporting.

Machine Learning and Deep Learning -- A review for Ecologists

1 code implementation11 Apr 2022 Maximilian Pichler, Florian Hartig

Finally, we summarize emerging trends such as scientific and causal ML, explainable AI, and responsible AI that may significantly impact ecological data analysis in the future.

BIG-bench Machine Learning Causal Inference

A new method for faster and more accurate inference of species associations from big community data

1 code implementation11 Mar 2020 Maximilian Pichler, Florian Hartig

Our sjSDM approach makes the analysis of JSDMs to large community datasets with hundreds or thousands of species possible, substantially extending the applicability of JSDMs in ecology.

Inferring species interactions using Granger causality and convergent cross mapping

1 code implementation2 Sep 2019 Frederic Barraquand, Coralie Picoche, Matteo Detto, Florian Hartig

Our results therefore imply that Granger causality, even in its linear MAR($p$) formulation, is a valid method for inferring interactions in nonlinear ecological networks; using GC or CCM (or both) can instead be decided based on the aims and specifics of the analysis.

Machine learning algorithms to infer trait-matching and predict species interactions in ecological networks

1 code implementation26 Aug 2019 Maximilian Pichler, Virginie Boreux, Alexandra-Maria Klein, Matthias Schleuning, Florian Hartig

Using simulated and real data, we contrast conventional generalized linear models (GLM) with more flexible Machine Learning (ML) models (Random Forest, Boosted Regression Trees, Deep Neural Networks, Convolutional Neural Networks, Support Vector Machines, naive Bayes, and k-Nearest-Neighbor), testing their ability to predict species interactions based on traits, and infer trait combinations causally responsible for species interactions.

BIG-bench Machine Learning regression

An Extended Empirical Saddlepoint Approximation for Intractable Likelihoods

1 code implementation8 Jan 2016 Matteo Fasiolo, Simon N. Wood, Florian Hartig, Mark V. Bravington

The challenges posed by complex stochastic models used in computational ecology, biology and genetics have stimulated the development of approximate approaches to statistical inference.
